Is the essence of ancient astronomy in China divination?

Admittedly, astrology was an important factor in ancient astronomy in China, but it was abrupt to raise it to the essential level. Astronomy began to enter people's field of vision in order to understand the laws of celestial bodies and formulate legislation to guide agricultural production. Then, combined with the national conditions of China, a set of system of harmony between man and nature was constructed and applied to astrology. When, why and how do most people use it? The answers to these two questions are definitely not astrology.

In addition, in fact, in the Song Dynasty, when science and technology were quite developed, someone wrote to Song Shenzong and said, "Eclipses and other astronomical phenomena can be predicted. Can you know in advance whether the warning in the sky is a warning in the sky? " Showed a quite scientific attitude. However, after repeated weighing, it is quite practical and necessary to introduce astronomical phenomena as a restriction of imperial power, and Song Shenzong finally accepted the theory of the unity of heaven and man. The reason for accepting is obviously not out of reverence for the stars.
